Kenmore Air Conditioner Capacitor Parts

OEM Kenmore Air Conditioner Capacitor Parts

Run capacitors are the hidden powerhouse of your Kenmore AC system—they store electrical energy that starts and keeps motors spinning. When a capacitor fails, your unit won't start, hums without cooling, or shuts down unexpectedly. Replacing a failed capacitor is one of the fastest, most cost-effective repairs you can make.

Kenmore air conditioners use run capacitors, dual-run capacitors, and start capacitors depending on model year and cooling capacity. Our OEM Kenmore capacitor parts are tested and matched to your exact unit specifications. Enter your model number to find the right capacitor, or browse our full Kenmore air conditioner capacitor parts selection below.

• Run capacitor (single): Unit hums but won't start, weak cooling, motor won't turn
• Dual-run capacitor: Both fan and compressor fail, no cooling or outdoor fan activity
• Start capacitor: Compressor clicks but doesn't start, repeated breaker tripping
• Capacitor mounting bracket: Loose capacitor, vibration noise, internal connections at risk
• High-voltage capacitor: Unit shuts down mid-cycle, erratic temperature control, electrical smell

Kenmore Air Conditioner Capacitor FAQs

How do I know if my Kenmore capacitor is failing?

Signs include humming with no cooling, unit taking longer to start, weak airflow, or complete shutdown. You may also notice a burnt smell or see the capacitor visibly bulged or leaking. Never open or touch a capacitor directly—they hold dangerous electrical charges even when powered off. Order a replacement based on your model number and have it installed.

What's the difference between a run capacitor and a start capacitor?

A run capacitor stays energized while the motor operates, providing continuous power stability. A start capacitor fires up the compressor briefly then disconnects. Kenmore units often use a dual-run capacitor that handles both functions. Your model number determines which type you need—order by the exact spec, not by guessing.

Where do I find my Kenmore model number for capacitor parts?

Look for a silver or white rating plate on the back or side of your outdoor unit. The model number is usually a 5-8 digit code starting with numbers or letters. Write it down exactly as shown, then use it to locate your matching capacitor. This ensures you receive the correct microfarad (µF) rating and voltage your system requires.

Can a bad capacitor damage my Kenmore compressor?

Yes—a failing capacitor forces the compressor to work much harder, drawing excess current and generating heat. Over time, this accelerates compressor wear and failure. Replacing a capacitor early (they're inexpensive) prevents a $500+ compressor replacement later. Don't delay if you suspect capacitor trouble.

Kenmore Air Conditioner Model Number: Where to Look

Kenmore typically places the air conditioner model number on the rating plate attached to the back or side of the unit. For a central system, check the outdoor condenser cabinet, and for a room unit, look along the side or behind the front grille. The model number may be near the serial number, so copy the complete code exactly, including letters, numbers, and punctuation. Type it into our model number lookup and the catalog narrows to parts made for your unit. This filters the full Kenmore air conditioner parts selection, not just capacitors, to parts that match your specific model. You order with confidence knowing the fit is right.
